Race strategy

Hold a steady pace and save energy for every section.

  • 303m descent. Go easy, save your quads.
  • The finish is runnable. Save your legs to run it all the way.
  • Long race. Control your HR and effort. Early mistakes cost the most.
  • Ease into the early runnable section, save your quads on the descents until 40.3km, then run your race pace.
  • Start · 0.0km–1.7km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.7km–19.9km · Plus 1 more climb. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
  • Work · 19.9km–54.1km · Descent of 303m averaging 7%. This is where the race is built: steady, solid effort. This descent is hard on the legs: short steps, stay in control, poles if you have them. Running pays off here: run wherever you can.
  • Fade · 54.1km–76.5km · Climb of 327m, high point 709m. Plus 1 more climb and 1 descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 76.5km–90.0km · 13.5km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.

  • #1 · 36.1–40.3 km · 303 m D−, -7.2% · 49.7 km ahead → control
  • 72.4–76.5 km · 340 m D−, -8.2% · 13.5 km ahead → your pace
